You don't find the Hadza colorful enough? It's not as though contemporary Chinese culture contradicts TFA's hypothesis.

Indeed!

I think there's a valuable lesson to be learned here: among the Hadza studied by ... every nursing mother is supported by a post-menopausal helper, nearly always her mother or mother-in-law.

Rather the opposite.

Haha, I haven't heard that piece of doggerel before. Where's it from? It sounds like my cousin. She just recently had a kid but it's mostly my aunt who takes care of the baby.

Also similar to what my early childhood was like before we moved to the states. Except my maternal grandfather passed away shortly after I was born and there was no internet back them.

I think the funniest thing is that it suggests that the modern Chinese family is uxorilocal when it's traditionally been virilocal.

It was told to me by a Shanghainese woman.

The same woman said that often the grandparents will move in with the parents to care for a child, rather than the other way around.

Ahaha, I knew it. My family is Shanghainese, and I was born and spent the first three years of my life there, so that makes sense.
